After cleaning a few things out of my house, I learned something new about eBay's Buy It Now option: on most items, it disappears after someone makes a bid. That means you're better off listing something with Buy It Now rather than as a straight auction.
Last week, I was selling something with a Buy It Now price, and was answering some questions with an interested buyer. Unfortunately, by the time I had answered all of his questions, someone had made a starting bid and he could no longer buy it straight away -- which he said he had wanted to do. The item ended up selling for half the Buy It Now price. If he had acted quicker, I could have made twice as much money.
Perhaps this is old news to some, but I never knew that the Buy It Now option disappeared a href="http://pages.ebay.com.au/help/buy/how-buy-bin.html">after one bid was made. So, despite the fact that eBay is an auction site, it might be worth making a fixed listing for certain items.
You may have to wait a little bit longer, but you have the potential to make more money than you would on an auction. The Buy It Now price has to be at least 30 per cent more than the reserve price. It could be worth experimenting; after al, if it doesn't sell after 10 or 30 days, you can always re-list it as an auction later.
